Let's divide 66028 by 21
We're looking to find how many times 21 goes into 66028.

Let's proceed to step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 21

Let's proceed to step 2:
If we divide 66 by 21, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 63 from 66 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 21

Let's proceed to step 3:
30 divided by 21 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 21 from 30 to get 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 21

Going ahead to step 4:
If we divide 92 by 21, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 314.0
The remainder is 8 after subtracting 84 from 92.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 21

Let's proceed to step 5:
If we divide 88 by 21, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 3144.0
The remainder is 4 after subtracting 84 from 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 6:
21 goes into 40 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 3144.1
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
190 divided by 21 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 3144.19
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
When dividing 10 by 21, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 3144.19
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
When dividing 100 by 21, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 3144.1904
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 3144.19047
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
When dividing 130 by 21, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 3144.190476
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
21 goes into 40 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 3144.1904761
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 13:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 3144.19047619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 3144.19047619 with a remaining 1e-09.
